Application led November 10, 1926. Serial No. 147,518.

My invention relates to a hogr spray of the typcvin which a gateway is provided through which a hog may pass and mechnnism actuated by the gate is adapted to spray oil upon the hogs back as hepasses through.

An object of my invention is to provide such-a spray which is of simple, durable and inexpensive construction, comprising a gateway, a tank mounted in the gateway and a pump for delivering the oil, including a cylinder and a piston actuated by the swing of the gate in either direction for spraying oil received from the tank.

A further object of the .invention is to provide-means foradjusting the stroke olf the piston in order to regulate the amount of oil delivered from the pump.

With these and other obJects 1n view,l myI invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings,'in which:

Fig. 1 is an elevation of the spray, parts being broken away to better illustrate the construction.

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a sectional view taken on the line 3-.-.3 of Fig. 2.

Fig. 4 is a sectional View taken on the line 4 4 of Fig. 2. i

I have used the reference character 10 to indicate generally the uprights or side membersot a gateway embodying my Spray.

The inem-bers 10 are connected by a bottom sill 11 and spaced upper cross pieces 12. A frame to support the tank lil is formed of a horizontal cross piece 14- and side cross piece 15 together with the cross pieces 12.

Oil delivering mechanism comprises generally an oil delivery spout cxtci'iding downwardly from the tank connected to a pump for withdrawing oil from the tank' and ejectinfr it `from the. spout and including check valves to control the action of the pump.

y The spout is thus composed of a T fitting 16 by means of which it is connected to the pump, a sleeve 17 connected to the T fitting 1G by means of a nipple 18, extended through thomember 14 and the valves 19 and 20 thread-ed into the sleeve 17 and nipple 18 respectively. The valve 19 includes a valve element or ball 21 seated to, close the opening;`- 22 by means ol a spring 22E, tho hitter bcing;- held in place -hy the usual threaded .sleeve l 24; The tank 13 is secured against a he.\-

afronal flange 24 on the valvcli) by means et) ot a nut 24J". The tank may be removed by .simply removing;r the'nutfll, inoider to allow cleaning ot' the impurities settling to the bottom ot' the tank from the oil. It will' be noted that by projecting. the valve 'into 65 the tank, the bottom layer of fluid willnot be drawn oil. i

The valve` 2O 'includes the valve element seated to close the opening '26 by ln'ieans dipen 'to allow oil to be drawnvinto the spout and into the pump while the valve Q() will be closed and that as the pump'begins itsv'` `compression stroke, that the valve 19 will i f l bf a spring 27 heldin place by the thrcndcd Y" l i l close and the valve 2O will bevopened under the pressure, to discharge oil from the opcning 29,-constinting the-nozzle ol theidcvicc.

-I't will now be seen thatI have provided 80 a very simple arrangement in which the oil container or tank, is conveniently mounted l in the-gateway directly above the gate and the nozzle projected directlylbelow the tank,

vAt problem of the present invention has 35,

been to provide means for actuating a pump connected with the oil delivery mechanism,

just described, in such a way that when the gate is swung in either direction, the oi'll will be sprayed upon thc back of the hog' during 9G the outward swing ot the 'gate and will thence be drawn into the pump as the gate` swings inwardly. Another problem in connection with the providingY of such a spray in which the oil is sprayedupon cach out- 95 ward movement ot' the gato is that ot stopplopY the swing of thc ,grate so that, as it K swings haelt to its normal position1 its nioincntum will not carry it any substantial distance beyond said normal 'iositioih "lhc .first problem is solvcd'in a simple manner by the use of a. double armed lever Il() brazod or'wcldcd to the shalt 31 which supports the gate 32 and forms :in integral part thereof. 'lho .shaft 3l is journallcd in 105 the sill 11 and the horizontal cross niember 14.

The double armed lever 30 is connectedto l theactuating mechanism of the pump, which will now he -dcscribed,vin sucha way that 110 when the gate is swung'in one direction one of the arms of the levers functions as a with the threaded caps 35 and 36, the former updn the T titting.16.

'of which is threadc( crank 'arm to gi'vefto the' `pump spraying mechanism its pressure stroke and when vthe gate is swung in the other direction', the

other arm will so functiom f l The pump includes a cylinder 34 provided The cylinder is rigidl secured against the horizontal member 14 )y means of a stirrup 3G encircling the cylinder and extended through the member 14 where it is secured at its ends by screws 36h.. The pistonl rod 87 i right 1-0' and which has its arms bent later-' is extended through the capiv and carries at its end withinfth'e cylinder 34 a piston 38;

I provide a yoke 39 of strap metal which isslidably mounted in an. opening lin the up a-lly as at 420 andI provided with openings 41 to receive the links 42 for connecting the yoke 39 to thelevcr 30. For the purpose of connecting the links 42 to the flanges 40,

- they arethreaded at their ends and provided with nuts 43' and 44,. the latter serving as loclcnuts. The vother ends of the'links 42 are extendedthrou'gh either of a pair of openings'45 in the respective arms of the lever 3G andthere secured as by Cotter keys 46. @ne of each pair oli openings is positioned closer `to the shaft 31 than itsv mate and` thereby ,the length of stroke of the piston can be adjusted since the effective en'gth of' thearms of thelever 30 is thus varied by shifting the links 42 fromone openingto the other.

' A spring 47 serves to 4urge theyoke 39 away from the pum 's 34,and"thus to move the piston. 3'8 in suc a direction as to cause the oil tobe drawn into the pumpy cylinder-'34. i The nuts 43 serve to l"adj-ust; the tension uporr-the springjll'. This is essential in order to reduce the swinging of the xgate after a hog has passed through.- VBy placing the spring under constant tension, also eliminate the' possibility of any freedom of movement between the links 42- and the yokcs f 39 which will allow the rate to move withoutcausi-ng the action ot the pump immediately.

Whe/n the'gate swings in one direction,

. such, for instance, as 'that indicated by the dotted lines vat 49, the lever of .the arm 30 on that side will pull the .link 42 and the yoke 39 in the directionl of the shaft 3l, thus causing the ypressure. stroke of the pump. Vhen the gate is swung in the other direction, the other lever will similarly lunction. The link wlricli'is not actingv to draw the yoke 39 inwardly. will be movedl in the opposite direction Aand -will slide tree into its opening 41., the latter opening also allowing the yoke 39 to slide forwardly rela tive to the l link'.

This is indicated in dotted lines of Fig. 2, the nuts 43l oonevot' thevlinksbeing shown in engagement with the member 40 in ita dotted linefpcsition and nuts 43* of the v other link'bcing shownl in a position moved away' from the corresponding,r member 40.

` 'It willl nnw be seen, in connection with the problem of stopping the swing of the gute after* an animal has passed throi1gh,-that thel ,gate must move against the action ofthe spring 47, each `tfme`1t moves outwardly in either direction, whereas, in moving toward closed position, it is under thev urge 0i" the.

Furthern'iorc, the action of the spring 47. pistou 38 within the cylinder 34 is similar to that of a dashV oli tlieygate. v l

v rThe blocks 50, which are secured to the under side 'ofthe member lI4, serve as guides for the yoke 39 to prevent tlieside arms, tliereoL'fro'm spreadingand' 'the cap' serves as a guide to prevent said' arms from i collapsing. inwardly. The blocks 50, in turni,

:serve as guides for the yolte 39' to'prcvent the side, arms, thereof, from spreading and' the cap 3G serves as aguidejio prevent sald pot in damping` the swing` arms from collapsing inwardly. vT he yoke 39, in turn, serves as a cage Jor the springl 47 and 1s aided 1n this bythe opening 1n the luprigl'itlO.

lit will be seen that l have providedl a very simple arrangement, obtamingall the desirable 4features of economy et construction; durability.7 conservation ofthe fluid used in spraying ma spray utilizing the principle offorcibly 'spraying the fluid upon the'bacle ot a hog. as he passes.
